This present invention relates to packaged moisture containing articlesand to procedure for producing the same. r i

Heretofore, many articles usually purchased in grocery stores such asmeat, fillets, chops, cuts, and steaks thereof, whole fish, fillets, andsteaks thereof, mm or game, whole, or Joints thereof, citrus fruits,tomatoes, grapes, cakes of soap and many other articles containingiroisture which is present at and may evaporate from the surface thereofhave been provided with envelopes or wrappers of various sheet materialsof the'nature of waxed paper, Cellophane, Pliofilm, Koroseal and othertough flexible transparent or translucent materials, in some cases, asin the case of Cellophane bags or envelopes, being sealed to preventloss of moisture from the packaged article.

Sealing of such bags or envelopes necessitates the use of adhesivesapplied locally to the bag or envelope along flaps or margins thereofand involve manufacturerof the bag or envelop, insertion of the moisturecontaining article theren, and finally sealing by the use of adhesivesor adhesive tapes appliedat the mouths of the bags or envelopes.

It has been discovered by the present inventor that sheet materialssucha Cellophane, Pliofihn,

, Koroseal, etc., which are tough, flexible, and

transparent and are coated with water-repellent, permanently-tacky,pressure-sensitive, clear adhesives of a known type applied over oneface thereof and which materials are on the market as Scotch tape orother trade names are capable of highly advantageous use a wrappers forthe previously enumerated articles. While this sheet material isstrongly adhesive to itself wherever laps, crimps, or. folds of thematerial are pressed together with at least one layer of the adhesive;

coating between the abutting faces of the sheet material, because of thecharacter of the surfaces of the article such as those enumerated andthe presence of more or less moisture therein, the

tacky water-repellent adhesive will not adhere str'ongly,-anc l in manycases will not adhere at all to surfaces of the articles against whichit maybe pressed, and will peel readily away from the article when thewrappers of suchmaterial are being removed.

In carrying out the present invention, toughflexible transparentmaterial havinga clear'adhesive coating of the kind described is merelywrapped and lapped in any convenient way about the article withthe'adhesive face against the article and projecting margins thereof arecrimped or folded to bring adhesive faces of the about the article whichmay. inevitably be entrapp d. Articles such as citrus fruits, meats,fish, fowl,

aged, expecially ifkept refrigerated, keep substantially all of theiroriginal water content, vitamins, and palatability without desiccation,putrefaction or decay and for indefinite periods of time,

l5 and do so without requiring the use of ice refrigeration.

mechanical refrigeration,'etc., have no appreciable dehydrating or othereffect upon the contents of the packages.

Fillets of meats, fish, etc., have heretofore had ordinary sheetwrappers of Cellophane or the like applied about them but have requiredice refri'geration for their preservation. By use of the presentinvention-this expensive and troublesome 26 icing may be avoided, dryrefrigeration being entirely satisfactory.

The packages are, of course, complete germ and vermin proof, and thusnot onlypreserve the. moisture within the article, but prevent ingressof i dirt and "foreign matters of all kinds;

I The packages, being transparent permit handling as well as visualinspection to note the Weight, feel, color, and texture of theipackaged,

contents without danger of contamination. v For purposes of illustrationof the invention, there is shown in the accompanyingdrawing an orangebeing packaged in accordance with the present invention.

Of the accompanyin drawing:

" herein may be different articles containing moisture present atsurfaces thereof which comprises orange as indicated in Figure 2 withover-lapping margins of the sheet pressed together, and finally theprojecting portions of the wrapper are crimped and pressed snuglyagainst the surface of the orange, the folds or crimps adhering to Toremove the wrapper it may be cut and readily peeled from the orange, ora thread or band (not shown) as is well-known in the art of packaging,may be incorporated in the wrapper. a projecting end of which may begrasped and pulled to sever the wrapper.

It will be apparent that the invention disclosed applied in thepackaging of many their surfaces and of a surfac texture such that theadhesive will not adhere to the surface of the article or will onlyslightly adhere. The invention is operable in thismanner with .manydifferent articles of similar surface characteristics to thosespecifically mentioned.

Modifications of the invention may be resorted to without departing fromthe spirit thereof in the scope of the appended claims.

What is claimed is:

1. An article containing moisture which is mor I or less present at thesurface thereof and having tough flexible transparent sheet materialwith a face 'coated with clear, permanently-tacky, pressure-responsive,waterrepellant adhesive wrapped snugly about the article with theadhesive-coated face applied against the article, said wrapper crimpedor folded about the article so as snugly to encase the same with thelaps and crimps or folds pressed together whereby the adhesive seals thewrapper about the article completely to seal the article therein, saidadhesive having little or no adherence to the surface of the article sothat it may be readily peeled therefrom'to remove the wrapper, and saidwrapper containinglittle' or no air excepting that which may'inevitablybe entrapped during the wrapping process;

2. That method of packaging moisture-containing articles havingmoisture-present at the applying a sheet of tough flexible transparentmaterial having a thereon a wrapper of permanently tacb',water-repellent, pressure-responsive adhesive on oneface thereof aboutthe article with said adhesive-coated face against the surface of thearticle and lapping and crimping or folding the wrapper snugly about thearticle while pressing the laps and crimps or folds together so assnugly and completely to encase the article with exclusion of all airexcepting such small quantities as may be entrapped during the wrappingprocess.

3. An article containing moisture which is more or less present at thesurface thereof and having thereon a wrapper of tough flexibletransparent sheet material with a face coated with clear,

permanently-tacky pressure-responsive, waterrepellent adhesive wrappedsnugly about the article with the adhesive-coated face applied againstthe article, said wraper having its overlapping margins adhesivelysecured together and then being lapped and crimped or folded about thearticle so as snugly to encase the same with the laps and crimps orfolds pressed together whereby the adhesive seals the wrapper about thearticle completely to seal the article therein, said adhesive havinglittle or no adherence to the surface of the article so that itmay bereadily "peeled therefrom to remove the wrapper, and

being lapped and 5 said wrapper containing little or no air exceptingthat which may inevitably be entrapped during the wrapping process.

4. The method of packaging moisture-containing articles having moisturepresent at the surfaces thereof which comprises applying a sheet oftough flexible transparent material having a permanently-tacky,water-repellent, pressure-responsive, adhesive on one face thereof aboutthe article with said adhesive-coated face against the surface of thearticle, overlapping opposed marginal portions of the sheet andadhesively securing the overlapped portions together, and lapping andcrimping or folding the wrapper snugly about the article while pressingthe laps and crimps or folds together so as snugly and completely toencase the article with exclusion of all air excepting such smallquantities as may be entrapped during the wrapping process.
